Mother's Day: Surprise Phone Calls From President Obama Leaves Moms Speechless

— -- Most moms hope to get a hug or a call from their kids on Mother's Day. What they definitely don't expect is a call from the commander-in-chief.

But President Barack Obama decided to make this Mother's Day a holiday three American moms would never forget.

All three women had written letters to Obama and were reportedly told to expect a call on from a White House official.

When they heard the president’s voice on the line Wednesday, they could hardly believe their ears.

“No way!” exclaimed Patricia Church, a 50-year-old single mother of four.

“Way,” Obama chuckled.

“You still don’t believe me? No it’s me! Okay, give me a test ... Ask me about anything,” the president offered, as another mom was left speechless.

“I know how tough it is to raise kids and do right by ‘em. If it hadn’t been for my mother, I certainly wouldn’t be here,” he said. “You’re doing the most important work there is.”

Stephanie Tarr, a mother to two boys, ages 9 and 3, described the experience as "surreal."

“He was very encouraging about the boys having a bright future,” Tarr told the Minneapolis Star Tribune. ““I was just in complete shock that this was happening.”

Obama’s own mother, Ann Dunham, died of ovarian cancer 1995.
